Abstract

A display driving chip and a liquid crystal display device are provided. The display driving chip including chip body and an enable signal generation module. The chip body is configured to provide a power supplying voltage to a power supplying end of a first comparator and to output a driving signal when an enable signal is at a high electrical level and an input voltage is greater than a predetermined under-voltage lock out (UVLO) voltage, and configured to stop from providing the power supplying voltage to the power supplying end of the first comparator and from outputting the driving signal when the enable signal is at a low electrical level or when the enable signal is at the high electrical level and the input voltage is less than or equal to the predetermined UVLO voltage.
